Hello everyone
I am your new “old” friend, Mr. Fu
Study the anorectum for most of my life
I always want to chat with you
Today’s topic: Intestinal polyps, is it a precursor to cancer?
Conclusion first:
80% of colorectal cancers
From polyps[1]
Remember the old man’s words:
High attention, but don’t be nervous
Body changes
Is a mark of the passage of time
Intestinal polyps, an unwanted dangerous molecule
Simply put, it’s a piece of extra “meat”
Its incidence, age 40 is a watershed
Under 40: about 20%~30%
Over 40: Up to 40%~50%[2]
It is a small raised mass
0.3~1cm
When more than 1 cm
Increased cancer risk
nasal cavity, vocal cords, stomach, gallbladder, bladder, large intestine
It’s all possible places
Intestinal polyps are the most insidious and cunning
Why?
Old man, I will analyze its tactics for you
Tactic 1: Choose Terrain to hide yourself
The large intestine consists of two segments, the colon and the rectum, like a gate
1.5 meters in length, winding and many folds
Suitable for polyps hidden here
Tactic 2: Quietly cancerous without giving you early warning signs
With petite stature and unique growth position
Its presence makes you completely indifferent
There is no suspicious phenomenon in the number, color and frequency of poop
The enemy is in the dark and you are in the light
It grows slowly and happily
It takes about 5~15 years from polyp to cancer[3]
Unintentionally
One day, a poop warning:
The number of bowel movements increases, and there is a feeling of endless bowel movements
Thin shape, grooved, bloody
The closer to the anus, the brighter the color of blood in the stool
Stool with lumps
Also, bloating
Wait until you find something unusual
It may be cancerous
Strategy one: early detection and early treatment
01. Preventive Checks:
Meet the following criteria
A colonoscopy is recommended regardless of symptoms:
1. Over 40 years old
2. Immediate family members with the disease
02. Surgery:
Removal or excision is recommended in benign stages
Listen to the doctor for specific circumstances
Strategy Two: Dietary Prevention
Appropriately reduce high protein and high fat
Fried food, quit smoking, cut down on alcohol
Intestinal polyps, more than one side
There are three kinds of images
There are two factions:
benign, malignant
But what is benign can become malignant
There are three schools according to the pathological characteristics:
Proliferative, inflammatory, adenomatous, see picture for details
Malignancy rate of adenomatous polyps[4]:
Diameter: less than 1 cm is about 1%
Adenomatous polyps have 3 branches:
Tubular adenoma, villous adenoma, mixed adenoma
Finally paralyzed fluid dissection instrument.
Gastroenterology, anorectal, and general surgery are acceptable
The bowel cancer time bomb must be cleared early
Everyone, love yourself
The long journey of life
Let the enemy of disease come later
Many veterans will continue to work hard
I will protect you
Ok, that’s it, what else do you want to know
